Laying device, contacting device, Zustellsvstem, laying and contacting unit, manufacturing plant, method of manufacture and a transponder unit

The invention relates to a laying device for laying wire windings in transponder units, in particular for the production of smart cards, a Kontaktiervor¬ direction for contacting the wires according to the preamble of claim 20, a delivery system for delivering processing devices according to the preamble of Claim 30, a laying and contacting unit according to claim 35, a manufacturing plant for the production of transponder units according to the preamble of claim 38, a process for the production of transponder units according to the preamble of patent claim 55 and a transponder unit according to the Oberbe¬ handle of the claim 60th

Transponder units are used, for example, in chip cards, such as biometric passports. They are used for storing and transmitting information and consist essentially of a wire coil, which is composed of ein¬ individual wire windings, and is connected with their end portions with a chip. The wire coil serves as an antenna for transmission and information on the chip. The transponder unit is usually introduced directly into a substrate. The embedding of the wire in the substrate or the connection of its end portions to the chip takes place via ultrasonic or thermal welding. In known chip cards, the chips are arranged on a chip module for enlarging their connection surfaces and are positioned on the latter via this substrate.

On such smart cards is disadvantageous that are increased by the chip modules substantially the cost of materials.

An apparatus for producing such a chip card is shown in EP 0 880 754 B1. The laying device has a sonotrode and an ultrasound converter for acting on an insulated wire guided in the sonotrode with ultrasonic vibrations. As a result of the vibrations, the wire is heated with its insulation and "hammered" into the substrate during installation.

A disadvantage of this solution is that the wire is seit¬ Lich introduced into the sonotrode, whereby a helical bore for receiving the wire must be formed in the sonotrode and the sonotrode has a complex geometry. The threading of the wire in the oblique bore is done manually, which is correspondingly time consuming and costly.

A known contacting device for connecting the end sections of the wire to the chip has a thermo¬ de, which is heated and pressed against the end portions, so that by temperature and pressure of the wire, these are welded to the chip. The thermode is arranged between clamping bodies, which are clamped together by means of clamping screws.

The disadvantage of this solution is that to change the thermode, the clamping screws must be released manually. For feeding a laying device or Kontak¬ animal device usually spindle motors are used, which are connected to dampen overshoots of the motors via damping elements with the respective Vor¬ direction.

However, spindle motors have limited dynamics. In addition, unwanted vibrations are introduced into the delivery system via the damping elements. Furthermore, spindle motors require a separate Bremsme¬ mechanism to prevent unwanted shifts in the vertical direction due to gravity.

According to EP 0 880 754 B1, in known processes for the production of chip cards, the wires are subjected to vertical ultrasonic vibrations during laying on the substrate. That the ultrasonic oscillations extend in the longitudinal direction of the sonotrode leading the wire.

A disadvantage of these methods, however, is that contaminations, for example wire insulation, can be "hammered" into the substrate.

For the industrial production of smart cards, several laying devices and contacting devices are combined in a manufacturing plant. Such systems are usually constructed in gantry design. A known gantry design is disclosed in EP 0 880 754 B1. The portals essentially have two vertical supports positioned on entge¬ gengesetzten longitudinal sides of a machine bed and one, the vertical supports interconnecting cross member. The devices are sorted according to the order of the working steps in groups arranged on the cross members next to each other. assigns and deliverable via a vertical movement of the cross member in the vertical direction.

The gantry design has the disadvantage that the accessibility and thus the observability of the production process are severely limited due to the vertical supports. Furthermore, it is disadvantageous that a space available at the cross members for fastening the processing devices is greatly limited, so that the productivity is severely limited.

The object of the present invention is a laying device for laying wires of a transponder unit, a contacting device for contacting the wires, a feed system for feeding processing devices, a laying and contacting unit, a production line for producing transponder units to provide a method for the production of transponder units and transponder unit, which eliminate the aforementioned disadvantages and allow safe and cost-effective production.

This object is achieved by a Verlegevorrich¬ device with the features of claim 1, a contacting device with the features according to the patent claim 20, a delivery system with the features of claim 30, a laying and Kontaktierein¬ unit with the features to claim 35, a manufacturing plant with the features according to the patent claim 38, a method having the features of claim 55 and a transponder unit having the features of claim 60.

A laying device according to the invention has a sonotrode for laying the wire on a substrate and an ultrasonic converter for acting on the sono electrode with ultrasonic vibrations. According to the invention, the wire can be fed axially to the laying device.

The axial wire feed has the advantage that no oblique bore must be formed in the sonotrode and the sonotrode is accordingly easy to carry out. Due to the simplified design of the sonotrode their weight can be reduced, which allows an increase in the ultrasonic vibrations, for example from the usual 40 kHz to about 60 kHz.

A preferred embodiment provides an axial passage for receiving the wire, which passes through the laying device axially.

In order to minimize the friction of the wire in the passageway, the wire may be guided via an air bearing in the passageway. For this purpose, a radial bore for injecting compressed air can be provided in a wire insertion region of the through-channel. It may be advantageous to heat the compressed air to about 50 ⁰ C to 60 ⁰ C in order to achieve a preheating of the wire or its insulation and to shorten the cycle time for laying gene.

One embodiment provides to improve the air bearing, the passage in the head region of the sonotrode to taper radially to form a kind of back pressure. If, for example, the diameter of the through-channel is 3 mm, then it is preferably reduced in the head region to approximately 300 μm measured over an axial length of approximately 2 mm to 3 mm from its outlet opening.

In order to minimize wear of the sonotrode at the outlet opening, it is advantageous if the sonotrode de rotatably mounted in the laying device, so that the wire is not applied to a local region of Aus¬ outlet opening, but comes into contact with a plurality of local areas, so that in operation, the entire peripheral area of the outlet opening is cut evenly loaded sections. Such rotational movements can be achieved in that the ultrasonic transducer is mounted in a floating manner, preferably by means of aerostatic guidance. In this case, the ultrasound converter can be designed with two annular shoulders which delimit an annular space to be blown with compressed air, preferably in the range of approximately 6 bar.

In order to automate a feeding of the wire to the through-channel, a feed device can be provided which grips the end section of the wire to be inserted and inserts or fills it into the through-channel. In this case, an embodiment provides for the feed device to be designed like a claw and relatively movable relative to the laying device.

The ultrasonic converter can in principle be arranged as desired to the sonotrode. In one embodiment, it is positioned with its longitudinal axis coaxial with the longitudinal axis of the sonotrode, the passageway extending therethrough. In another embodiment, it is arranged laterally to the sonotrode. The lateral arrangement has the advantage that the sonotrode is even easier to carry out and thus the laying device can be operated at even higher frequencies, for example beyond 100 kHz. In the case of the lateral arrangement, the introduction of the ultrasonic waves into the sonotrode preferably takes place transversely to its longitudinal axis, ie in the horizontal direction. In a preferred embodiment, the Längs¬ axis of the ultrasonic converter is offset by an offset radially offset to the longitudinal axis of the ultrasonic converter housing.

In another preferred embodiment, the wire can be freed from its insulation within the laying device.

A contacting device according to the invention for contacting wires, in particular with chips, has a clamping arrangement for clamping a thermode. According to the invention, the clamping arrangement has clamping jaws which are automatically biased against each other, so that the thermode is clamped.

An advantage of this solution is that the manually operated clamping screws omitted.

In a preferred embodiment, the Klemm¬ arrangement has a fixed and a movable clamping jaw, wherein the movable jaw forms like a lever and is biased by a spring against the fixed Klemm¬ jaw. Preferably, the spring is supported on the fixed jaw.

To release the clamping, a displaceable wedge element can be provided, which can be brought into abutment with a wedge surface on an inclined surface of the movable clamping jaw, so that the movable jaw can be swiveled and the spring can be compressed by displacement of the wedge element. This mechanism allows an automated change of the thermode and thus makes it possible to shorten the thermode changeover time or the shutdown time of the contacting device. The thermodes can be kept in a magazine, which is used to remove a new thermodes can be controlled accordingly by the contacting device.

In order to improve the contacting or to avoid dangerous gases when contacting protective gas can be used, which flows around the tip of the thermode during operation. As a protective gas supply, protective gas channels can be formed in the clamping jaws, which in the head region of the clamping jaws, i. at an axial distance of about 1 mm from the tip of the thermistor, emerge from it. The protective gas supply can be optimized via a valve and a sensor for measuring the protective gas parameters, in particular the volume and the pressure. An extraction of the protective gas can be realized via a cup-like suction hood, in the interior of which dive the jaws with the thermode.

A feed system according to the invention for feeding processing devices, such as the laying or contacting device according to the invention, has a connecting carriage for connecting the machining device and a drive for moving the connecting carriage. According to the invention, the drive is a piezoelectric motor which functions according to the piezo-leg principle.

Such a delivery system has the advantage that it has a very high dynamics. Furthermore, the Zu¬ stellstelling system is small and weight-saving executable because, for example, due to the self-locking of the piezo motor in NichtbeStrömung a separate brake mechanism can be omitted.

In one embodiment, the piezo motor is formed with a multiplicity of fingers, which, when energized, form an s-shaped path, ideally a sine curve, tread. In this case, at least one finger acts on a slide, which cooperates with the connecting carriage and is preferably made of ceramic. The movement of the fingers is transmitted to the slider, causing it to perform a linear movement. For better longitudinal guidance of the slider may rest with a remote from the fingers on a guide shoulder and be attached with its free end portion to a guide carriage, which is connected to the connecting carriage for the processing device.

The guide carriage may be indirectly or directly connected to the connecting carriage. In the case of an indirect connection, a load meter, in particular a force meter, is preferably arranged between the two carriages, via which the displacement of the slide can be measured, so that it is possible to intervene in the control of the piezo motor. In addition, the strain gauge can take on damping tasks and thus overshoot the piezo motor within certain limits, preferably up to 100 microns, compensate. A known damping with a spring element can therefore be dispensed with, whereby negative vibrations can be avoided and the high dynamics of the piezoelectric motor can be transmitted to the connecting slide.

A laying and contacting unit according to the invention has a laying device according to the invention and a contacting device according to the invention. The spatial summarization of the laying and the contacting device has the advantage that space saving two methods can be performed durch¬.

In a preferred embodiment, the laying device and the contacting device are arranged in a common holder, which can be connected via two The delivery systems according to the invention can be moved in the x and y directions. In the x-direction, this means a feed in the longitudinal direction of a machine bed and in the y-direction means a displacement in the plane transverse to the longitudinal direction of the machine bed. For delivery in the z-direction, ie in the vertical direction, the devices can preferably be arranged individually on a respective delivery system according to the invention.

A production plant according to the invention, in particular for the production of chip cards, provides a placement station for equipping the substrate with a chip, a laying station for laying a wire on a substrate, and a contacting station for contacting the wire with the chip. According to the invention, the stations are arranged on brackets which can be moved individually in the x, y and z directions.

Compared with the known solutions, such as the gantry design mentioned at the outset, this console construction has the advantage that the accessibility and the possibility of observation are increased, since no vertical supports obstruct the space at the machine bed and the view. Preferably, the cycle time is about 10 s.

In a preferred embodiment, the Konso¬ len are arranged on a longitudinal side of a machine bed and designed like a cross slide, where they are about be¬ known spindle or linear actuators movable. The individual stations consist of a multiplicity of known loading devices or the laying devices according to the invention or the contacting devices according to the invention.

Of course, however, the Verlegestati¬ on with the contacting station on a console to a Laying and Kontaktierstationseinheit be summarized. Such a station unit is then formed by a multiplicity of the laying and contacting unit according to the invention, wherein such a laying and contacting station unit of the mounting station would be switched on.

The productivity of the manufacturing plant can be increased if the individual devices, in contrast to the known gantry design not only side by side, but flat, i. both side by side and in succession, are positioned on the consoles. For example, thus about 10 devices can each form a station.

The delivery of the individual devices in the z-direction can take place via "individual delivery systems according to the invention.

For punching chip windows into the substrate, a film dancing station can be provided, which is displaceable on the machine bed in the x direction. Preferably, the film dancing station is designed as a window punch that satisfies the highest requirements of accuracy.

Likewise, a cutting station for subdividing the substrates provided with the transponder unit into handwritten processing units. The separating station can be moved on the machine bed in the x direction and equipped with an ultrasonic knife for optimizing a sectional image. The flexibility of the entire production plant can be increased if the cutting station is freely programmable such that a roll-sheet and / or roll-roll processing without conversion is possible. In order to improve adhesion of the laid wire windings on the films or the use, a coating station for applying a coating to at least the surface regions of the film or the benefit can be provided into which the wire windings are introduced.

In another preferred embodiment, the transponder units may be made from individual sheets which may be manually fed to the manufacturing line and subsequently manually removed after processing. This embodiment is particularly suitable for small series and allows individual placement of the transponder units. For this purpose, the manufacturing plant may comprise at least one carriage for receiving a sheet to be loaded, which is movably guided on the machine bed and the individual consoles anfährt. For returning the carriage, a return may be provided by which the carriage is returned to its initial position, i. H. the position in which the sheet to be processed has been placed on the carriage, can be guided, so that the removal of the loaded sheet from the returned carriage and placing a new sheet on this carriage can be performed by an operator. Advantageously, the return in the machine bed is angeord¬ net, so that no additional space next to the manufacturing plant is required by the return.

In order to prevent slippage of the sheet on the carriage, a mechanical or a magnetic clamping device may be provided for clamping the sheet on the carriage.

In another embodiment, both a mechanical and a magnetic clamping device are provided. hen attacking at remote edge areas of the arc. In this case, the edge regions preferably extend in the feed direction of the carriage.

The mechanical clamping device can be fixed in position on the carriage and have a clamping claw spring-tensioned in the clamping position.

The magnetic clamping device may have any positionable on the carriage terminal strip with a magnetic tape.

An inventive method for producing a transponder unit provides to apply to the wire when laying on the substrate with ultrasonic waves that are parallel to the laying plane. That The ultrasonic waves are introduced into the wire in a horizontal direction to the longitudinal axis of the sonotrode feeding the wire.

It is advantageous in this solution that the wire is "rubbed" into the substrate, as a result of which contamination, for example its insulation, is released and the laying quality is correspondingly improved. Furthermore, tooling costs can be reduced.

Preferably, the horizontal Schwingungsbe¬ implementation is applied in direct contacting. When directly contacting the wire is connected with its Endabschnit¬ th directly to pads of the chip. That it is dispensed with the usual chip modules to increase the contact surfaces.

A transponder unit according to the invention produced by direct contacting is characterized by the direct contacting and the omission of the chip module by a reduced number of parts and reduced manufacturing costs.

An embodiment of direct contacting provides for positioning the chip in a chip window of a substrate. Subsequently, an end portion of the wire is introduced into the substrate under the action of ultrasound, wherein the wire is guided over a first connection surface of the chip. After crossing the chip, the wire is thermally welded to the first pad of the chip. The laying of the wire under ultrasonication is continued until the desired wire coil forms on the substrate, the wire finally crossing the threaded wire windings and passing over a second pad of the chip. To contact the wire with the second pad, the wire is welded to it.

A preferred frequency range of the ultrasonic oscillations is about 100 kHz.

When crossing the laid wire windings and / or when crossing the connecting surfaces, the ultrasonic application can be suspended.

For cutting the wire after the welding with the second connection surface, the wire can perform a return movement, whereby it is torn in the region of the weld. The retraction movement can be facilitated by means of the feed device according to the invention.

As a preferred installation device and / or contact device, a laying and contacting unit according to the invention can be used. Other advantageous embodiments are the subject of further subclaims.

According to FIG. 1, an embodiment of a laying device 2 according to the invention for laying an insulated wire 4 as an antenna on a substrate 6 for producing a transponder unit, for example for chip cards or for laying antennas in mobile phone housings, has a tubular housing 8 An ultrasonic converter 10 and a sonotrode 12. According to the wire is axially fed to the laying device 2. To guide the wire 4, a coaxial wire guide in the form of a through-channel, which is composed of several individual bores 14, 15, 44, 54, is formed in the laying device 2.

The ultrasonic converter 10 serves to act on the sonotrode 12 and thus of the wire 4 with ultrasonic oscillations in the range of approximately up to 60 kHz. He has a cylindrical body which is penetrated by a longitudinal axis of the sonotrode 12 coaxial through hole 14 for receiving the wire 4. With two end-face annular shoulders 17, 19 it enters two end-side recesses 22, 24 of the housing 8, an annular space 16 being formed between its outer circumferential wall 25 and an opposite inner circumferential wall 27 of the housing 8.

The annular space 16 is axially bounded by annular shoulder surfaces 16, 18 of the annular shoulders 17, 19 and a sealing ring 26 which dips into an end-side annular groove of the recess 20 and rests against the annular shoulder surface 18 axially, and via a sealing ring 26 in an inner circumferential groove of Housing 8 dips and at a portion of the outer peripheral wall 25 of the ultrasonic transducer 10 rests in the circumferential direction abgedich¬ tet. With its second annular shoulder surface 20, it rests flat against an opposite bottom surface 28 of the recess 20. Preferably, a radial clearance of the ultrasonic converter 10 in the housing 8 is about 20 microns and an axial clearance about lOOμm.

Via a transverse bore 34 with an internal thread, a gaseous or liquid medium can be introduced into the annular space 16, so that the ultrasonic converter 10 is mounted floating and in operation due to the generated ultrasonic vibrations can perform both rotational movements and axial movements. Preferably, compressed air is injected at a pressure of about 6 bar into the annular space 14.

The ultrasonic converter 10 is connected via a stirnsei¬ tiges radially stepped back converter horn 36 with a cylindrical shaft 38 of the sonotrode 12 in connection. The converter horn 36 is preferably screwed to the ultrasonic converter 10 and has an axial bore 15 coaxial with the longitudinal axis of the sonotrode 12. The converter horn 36 is also screwed to the shaft 38 of the sonde. As indicated in FIG. 1, it additionally has an end-side centering recess 40 in which a centering projection 41 of the sonotrode 12 engages. The centering has the advantage that the axial bore 15 of the shaft 36 is positioned exactly coaxial with the longitudinal axis of the sonotrode 12.

The shaft 38 merges into a conical head region 42 of the sonotrode 12. In the sonotrode 12, a through hole 44 is formed coaxially to the longitudinal axis, which extends from the centering projection 41 to an end-side outlet opening 46 in the head region 42. For better guidance of the wire 4, the through hole 44 is radially tapered in the region of the outlet opening 46. Preferably, the through-bore 44, viewed at an axial length A of about 2 mm to 3 mm from the outlet opening 46, has a diameter of 300 μm.

A bearing device 48 is arranged on the end face of the ultrasonic converter 10 opposite the sonotrode 12. The half-body 50, 53 are connected to each other at the front so that in each case one, the half-body 50, 52 axially passing conical Recess forms in cooperation with the other recess an interior 54 with an approximately diamond-shaped longitudinal cross-section. In this case, the conical recess of the upper half body 50 shown in FIG. 1 has an inlet opening 58 for the wire 4.

The wire guide is composed in the laying device 2 from the interior 54, the through hole 14, the axial bore 15 and the longitudinal bore 44 together. Consequently, the laying device 2 is penetrated coaxially with the longitudinal axis of the sonotrode 12 by a through-channel. Preferably, the passageway has a diameter of 3 mm, which as described above in the head region 42 of the sonotrode 12 is reduced to about 300 microns. In particular, the end-side arrangement of the inlet opening 56 permits an axial feed of the wire 4.

Via radial bores 58, 60 or a bore star, a gaseous medium can flow into the interior 54 and thus into the wire guide, which serves for the low-friction guidance of the wire 4. Preferably, compressed air is used, so that the wire 4 is guided by means of aerostatic storage in the wire guide almost smoothly. In this case, due to the tapered region in the through-bore 44 of the sonotorde 12 in the region of the outlet opening 46 forms a back pressure, through which the guide is improved.

To shorten the cycle time for laying the compressed air can be preheated. A preferred Temperatur¬ range is about 50 ° C to 6O ⁰ C. By preheating in particular the insulation of the wire 4 is heated, so that the connection with the substrate 6 can be done faster. For feeding and threading the wire 4 into the inlet opening 56, a feed device 62 is provided. The feed device 62 essentially has two grippers 64, 66, of which at least one is movably mounted on a holder 68, so that a threaded end section of the wire 4 can be gripped and guided in a targeted manner. The holder 68 is displaceable relative to the laying device 2, it also being able to carry out a backward movement with appropriate control. By a repeated loosening, retracting, gripping and ancestors of the Vorschubein¬ device 62, the wire 4 can be automatically transported step by step to the outlet opening 46. Thus, it is possible, for example, to feed the wire 4 with its free end section via the laying device 2 into an opening of a closed housing and then to move it to the outside of the housing on the latter.

A backward movement is particularly advantageous when the wire 4 is to be separated after laying and contacting. In such a case, the wire 4 can be torn by a backward movement in the region of the contacting (see FIG.

In a preferred embodiment, according to FIG. 1b, the ultrasound converter 10 is arranged offset in the housing 8 in the radial direction, so that the passage channel composed of the individual bores 14, 15, 44 and 54 runs eccentrically to the housing longitudinal axis G and the outlet opening 46 by an offset V radially offset from the housing longitudinal axis G is arranged. In this case, the wire 4 is fed via the feed device 62 coaxially to the longitudinal axis L of the through-channel, so that it is guided "centrally" in the through-channel. Preferably, the offset V between the housing longitudinal axis G and the longitudinal axis L of the passageway about 0, 5mm.

The eccentric orientation of the through-channel to the housing longitudinal axis G has the advantage that the outlet opening 46 of the sonotrode 12 is displaceable relative to the housing 8 by rotations of the ultrasonic converter 10 about its longitudinal axis. This makes it possible, in particular, to adjust the position of the laying devices 22 relative to one another in a multiplicity of identical laying devices 22 for producing a plurality of transponder units. Thus, it is conceivable, for example, to arrange twelve laying devices 22 in a console or station (cf. FIGS. 5, 6 and 7) which is explained below, wherein in each case six laying devices 22 are arranged in the feed direction (x). Direction) behind each other and two laying devices 22 are arranged transversely to the feed direction (y-direction). The six laying devices 22 are each guided over their housing 4 in a common groove extending in the x-direction. In other words, the console has two grooves running in the x-direction, in each of which six laying devices 22 are arranged over their housing 4. To adjust the distances between the laying devices 22 mounted in each case in one of the grooves in the x-direction, the laying devices 22 are freely displaceable and fixable in the groove. For adjusting the laying devices 22 in one of the grooves in the y-direction relative to one another, the ultrasound converters 10 are rotated in their respective housing 8 until, due to the eccentricity of the longitudinal axis L of the through-channel to the housing longitudinal axis, the outlet openings 46 are optimal relative to one another in the y-direction are arranged. Furthermore, the laying device shown in FIG. 1b has a transverse bore 43 in the head region 42 of the sonotrode 43, which opens into the longitudinal bore 44 and into which a sleeve 45 is inserted through which a light waveguide or a glass fiber 47 passes which is in communication with a power source (not shown) such as a laser. The laser light is guided via the glass fiber 47 to the wire 4 in the longitudinal bore 44, as a result of which it is heated and its insulation evaporates away in a defined manner so that the wire 4 emerges from the outlet opening 46 as a bare copper wire and is embedded in the substrate 6 can or, as will be explained below (see Figures 2, 3 and 4), can be contacted by means of thermocompression welding with pads of a chip or contact surfaces of a chip module without the contamination introduced by the insulation during installation or Kontak¬ animals could be because it has already been removed. The transverse bore 43 preferably has a diameter of 2.6 mm.

Likewise, it is conceivable to blow heated air into the longitudinal bore 44 through the transverse bore 43 or the sleeve 45 in order to remove the insulation of the wire 4.

According to FIG. 1 a, a cooling device 182 can be provided to prevent overheating of the wire 4 to be laid. The cooling device 182 has a nozzle which is in communication with the compressed air supply of the aerostatic bearing device 48 of the laying device 2. The nozzle is arranged next to the head region 42 of the sonotrode 12 such that the wire 4 emerging from the longitudinal bore 44 or the outlet opening 46 can be flowed around by the compressed air. The cooling with compressed air has the advantage that this due to the air flow of the Wire 4 is already guided to the laying device 2 and thus no costly separate feed must be made. Of course, however, other gases are conceivable as a cooling medium.

Figure 2 shows a Kontaktiervor¬ direction 70 according to the invention for contacting a wire with a chip by means of temperature and pressure. Of course, the contacting device 70 can also be used for contacting a wire with a substrate. It has a clamping arrangement 72 for clamping a thermode 74 with a fixed and a movable jaw 76, 78, the head portions 80, 82 are biased by a spring 84 for clamping the thermode 74 against each other.

The contact is made by energizing the Klemm¬ arrangement 72, wherein in the region of the thermode tip 75, the largest resistance exists, so that it is heated and heated upon depression of the thermode tip 75 on the wire this, deformed and connected to the chip.

To accommodate the thermode 74, the head portion 80 of the fixed jaw 76 has an axial recess 86 formed corresponding to the thermode 74. The head portion 82 of the movable jaw 78 has a correspondingly shaped but axially shortened projection 88 Thermode 74 with its thermode tip 75 axially beyond the recess 86 and the projection 88 addition.

To receive the spring 84, a blind hole 94, 96 is formed in the jaw sections 80, 82 of the jaw sections 90, 92 of the jaws 80, 82, the spring 84 being supported on its base surfaces. The head portion 82 of the movable jaw 78 is pivotable about a pivot axis 98, so that the thermode 74 is automatically einge¬ clamped between the jaws 76, 78 einge¬. To release the clamping, a wedge element 100 is provided, which is displaceable in the longitudinal direction of the thermode 74. It has a wedge surface 102, with which it can be brought into abutment with a correspondingly shaped inclined surface 104 of the jaw portion 90 of the movable clamping jaw 78.

Upon displacement of the wedge element 100 in the direction of the pivot axis 98, the wedge surface 102 runs on the inclined surface 104, as a result of which the movable clamping jaw 78 is pivoted counterclockwise about the pivot axis 98 according to FIG. Consequently, the clamping of the thermode 74 is released and the spring 84 is compressed. For renewed clamping, the wedge element 100 is moved back until the contact between the wedge surface 102 and the inclined surface 104 is released, as a result of which the spring 84 is relaxed and the thermode 74 is clamped. Auf¬ reason of the automatic clamping of the thermode 74 thus a thermode change can be automated. The automated thermode change can be carried out particularly easily if the thermodes 74 are held in a magazine that can be activated by the contacting device 70.

In the clamping jaws 76, 78 at least one gas channel 106, 108 for supplying protective gas is ausgebil¬ det. For suction of the protective gas, a cup-like suction hood 110 is provided. The suction hood 110 has a coaxial opening 112 of its bottom plate, through which the clamping jaws 76, 78 can dive with their head portions into the interior of the suction hood 112. The exhaust hood 110 has the advantage that at the contact tion toxic gases, such as hydrochloric acid are evacuated. The gas channels 106, 108 extend at least in sections in the longitudinal direction of the contacting device 70 and emerge concentrically with the thermode 74 near the tip of the thermistor 75. In principle, the protective gas effect is the better, the closer the gas can flow in the axial direction along the thermode tip 75. Advantageously, the head portions 80, 82 have chamfered outer surfaces 114, 116, wherein the gas channels 106, 108 exit at about an axial distance of 1 mm from the thermode tip 75.

To control the amount of inert gas, in particular for the possibility of oxidation-free welding, a valve (not shown), preferably a proportional valve, is provided which cooperates with a sensor for detecting the protective gas parameters, such as pressure or flow, and the like Opening cross section is adjustable according to the detected parameters.

FIG. 3 shows a feed system 124 for feeding a processing device, for example a laying device 2 according to FIG. 1 or a contacting device 70 according to FIG. 2. Such a feed system 124 permits a linear movement of the processing device into an x, y, or z -Direction. According to this understanding, the x-direction corresponds to the horizontal transport direction in the longitudinal direction of a machine bed, the y-direction is the horizontal direction transverse to the machine bed, ie transversely to the x-direction, and the z-direction corresponds to the vertical to the machine bed, ie in the z-direction is a Hδhenverstellung. With the arrangement of three feed systems 124, the processing device can thus be displaced individually in all directions. The feed system 124 has a connecting slide 128 guided on a longitudinal guide 126 for connecting and displacing the processing device. In this case, the connection of the processing device via a corresponding hole pattern 130 on the connecting carriage 128. Furthermore, the feed system 124 has a drive 134 for driving the connecting carriage 128, which is arranged on a separately formed from the longitudinal guide 126 base plate 132.

The drive 134 is referred to as a piezo motor, i. a piezo-leg motor, executed by the connecting carriage 128 is longitudinally displaceable. The drive 134 has a multiplicity of fingers 136 or legs, the so-called piezo-legs, which, when the drive 134 is energized, form an s-shaped, ideally sinusoidal, path. In each case, a finger 136 acts on a front side of a slider 138, which is thus displaced linearly.

The slider 138 is preferably made of ceramic. In order to prevent deformation of the slide 138 when one of the fingers 136 is pressurized, it rests against a guide shoulder 140 in the region of the drive 134 with its rear side. With a free, remote from the drive 134 end portion it is attached to a guide carriage 142 which runs in a longitudinal guide 144.

The guide carriage 142 is connected to the connecting slide, so that the longitudinal displacements transmitted by the slide 138 to the guide slide 142 are forwarded to the connecting sheds 138 and thus to the machining device. Preferably the carriages 138, 142 are interconnected via a strain gauge 146.

The strain gauge 146 is preferably designed as a force meter and serves to measure the displacement parameters, such as displacement force. It is preferably provided in ZustellSystemen 124 in the z direction and designed such that it also has damping properties. For example, known strain gauge sensors are conceivable. These sensors usually have an E-shaped geometry, wherein a pressure sensor for measuring the pressure developed by the drive 134 and transmitted by the slide 138 is arranged on the middle beam of the E. The two outer beams of the E allow deformation and thus damping, preferably in the directional range of approximately 100 μm, so that certain force overshoots can be compensated.

Thus, additional damping elements such as compression springs between the carriages 138, 146 can be dispensed with. The omission of such damping elements has the advantage that no disturbing vibrations are introduced into the processing device and the high dynamics of the piezoelectric motor 134 can be transmitted to the connecting carriage 128 virtually unfiltered. Consequently, corrective action can be taken quickly and immediately in a laying and / or contacting process, so that particularly tight manufacturing tolerances can be maintained.

FIG. 4 shows a laying and contacting unit 117 with a laying device 119 and a contacting device 70 for producing a transponder unit by means of direct contacting. During direct contacting, a wire 4 is directly contacted with connection surfaces of a chip, which requires particularly high degrees of accuracy. Ie. it is dispensed with the usual chip modules to increase the contact surfaces of the chip. Of course, however, a combination of the Kontak¬ animal device 70 with the laying device 2 described in Figure 1 is conceivable.

In principle, the laying device 118 according to FIG. 4 is like the above-described laying device 2 according to FIG. 1 with an axial feed of a wire 4 and a coaxial wire guide, a conically tapered sonotrode 119, an aerostatic bearing device 48 and a gripping feed device 62 for feeding and threading the wire 4 into the passageway.

The essential difference to the laying device 2 according to FIG. 1 is that an ultrasonic transducer 120 is not fixed coaxially, but laterally on the sonde 119. The ultrasound converter 120 is offset, as it were, laterally to the longitudinal axis of the sonotrode 119, so that ultrasound oscillations are horizontal, i. in Quer¬ direction to its longitudinal axis and thus parallel to the laying plane of the wire 4, be introduced into the sonotrode 119 and the wire 4 thus "rubbed" by applying horizontal vibrations in the substrate.

On the shaft 123 of the sonotrode 119, the bearing device 48 is attached to the front side, so that consequently the axial wire guide does not extend through the ultrasound converter 120.

The lateral ultrasonic device 120 has a screwed on a narrow side converter horn 122, with which it engages around the extended shaft 123 of the sonotrode 119 by clamping. The clamping is for example by It can be produced that the converter horn 120 is formed as an axially slotted ring, which can be arranged on the shaft 123 in a force-fitting manner by means of clamping screws.

The ultrasonic converter 120 is floating, for example by means of the above-described air bearing, received in a holding element, not shown, by means of which the entire laying device 117 is supported. Thus, the ultrasonic converter 120 and the sonotrode 112 can perform free movements in operation. As a result of the lateral arrangement of the ultrasound converter 120, the latter and the sonotrode 119 can be made even smaller and lighter in weight, as a result of which even higher ultrasound frequencies, for example beyond 100 kHz, are made possible. In such a case, the sonotrode 119 has a maximum amplitude in the transverse direction of approximately 10 μm in the region of the outlet opening 46 of the through-channel. Thus, new processing methods such as the Direktkontaktierverfahren invention and corresponding transponder units can be realized.

The laying device 118 and the contacting device 70 are arranged in a holder, not shown, which is positioned in a central axis system. The holder can be delivered in x-direction and y-direction. In the z direction, the devices 70, 118 are individually deliverable. Preferably, a delivery system according to the invention according to FIG. 3 is used in each case as the delivery system, so that absolutely precise and highly dynamic motor rides are made possible.

In a method according to the invention for forming a transponder unit by means of direct contacting, ie for connecting the end sections directly to the contact surfaces of a chip without the use of a chip module, a chip is punched in a die cut chip. positioned window of a substrate. In order to prevent a relative change in position of the chip in the chip window, it can be secured in the chip window with an adhesive. Subsequently, by means of the feed device 62, a wire 4 is threaded axially into the bearing device 62 and thus leads to the sonotrode 12. For laying the wire 4, heated compressed air is blown into the air bearing device 48 and the ultrasonic converter 120 is driven, preferably at about 100 kHz, so that the sonotrode 119 is subjected to horizontal ultrasonic vibrations and the wire 4 is "rubbed" into the substrate. The free end portion of the wire 4 is fixed and guided the wire over a first pad of the chip. After crossing the first connection surface, the contacting device 70 is activated and the wire 4 is welded to the connection surface. The laying of the wire 4 under ultrasonic loading is continued until the desired number of wire windings or the wire spool has been laid. Finally, the wire 4 is passed over the threaded windings and over a second pad of the chip. It can not result in a short circuit due to the insulation of the wire 4 when crossing the already installed windings. To contact the wire 4 with the second connection surface, the contact device 70 is driven again. By depressing the wire 4 during welding to the thermode tip 75, the wire is heated, deformed and thus welded to the second pad. To sever the wire after successful laying and welding, the thermode tip 75 is held depressed on the wire 4. Subsequently, the feed device 62 grips the wire 4 and performs a backward movement, so that the wire 4 is loaded in tension and is torn in the area of deformation by the thermode tip 75, ie in the region of the weld. Thus, the transponder the unit finished and can be removed from the laying and contacting unit 117.

Optionally, the ultrasound application of the wire 4 can be suspended when crossing the laid wire windings or when crossing the connection surfaces.

During the entire process, the individual laying and contacting steps are monitored by an optical monitoring device. In the case of impermissible actual deviations from the desired deviations, the adjuster systems are actuated correspondingly so that the impermissible actual deviations are corrected or prevented from the beginning by an immediate readjustment.

FIG. 5 shows a production system 148 according to the invention for producing a multiplicity of transponder units.

The manufacturing facility 148 includes a machine bed 150 for transporting a utility 152. The utility 152 is moved by gripping means 154 in cycles, for example, every 10 seconds to individual processing stations located at consoles 156, 158, 160. By way of example only three consoles 156, 158, 160 are shown in FIG.

The brackets 156, 158, 160 are arranged on a longitudinal side of the machine bed 150. Thus, an operator from the opposite longitudinal side of the machine bed 150 has a clear view and free access to the processing stations. The brackets 156, 158, 160 are formed like a cross slide, whereby they are individually movable in the x-direction and in the y-direction. They are deliverable in the y direction in such a way that the total te width of the benefit 152 is traversable. The delivery can take place, for example, via spindle drives which are connected to corresponding cross slides mounted in the longitudinal guide.

Illustrative processing stations are beispielswei¬ se a stitching station for stapling a carrier web with a film in the chip window are introduced, for use, a loading station for populating the benefit with chips, a laying station for laying wires on the benefit and a contacting station for contacting the wires with the chips. In this case, the individual processing stations consist of a plurality of stapling devices, equipping devices, laying devices 2 according to FIG. 1 and contacting devices 70 according to FIG.

The individual devices are in each case flat next to one another and behind one another, i. in the x and in the y direction, arranged on the brackets 156, 158, 160, whereby a high productivity can be achieved. For example, it is possible to arrange 10 devices on a respective console 156, 158, 160.

Delivery of the devices in the z-direction takes place individually via in each case one individually assigned delivery system according to FIG. 3.

On the machine bed 150, a foil stamping station 160 for punching chip windows is initially arranged. It is preferably a window punch which can be displaced in the x direction, whereby distortions are prevented and very high accuracies can be achieved.

Opposite the bracket 158 for receiving the loading station is on the machine bed 150 a her- conventional module punching station 164 arranged for punching the chips with the chip modules from a delivered transport unit.

Further, on the machine bed 150, a cutting station 166 for cutting the benefit 152 into handleable processing units for simplified further processing, such as for example lamination, is arranged. The cutting station 166 has an ultrasonic knife and is freely programmable, i. Without the need for retrofitting, the cutting station 166 can perform roll-to-roll or roll-to-roll processing.

To produce a transponder unit, a film is passed through the film punching station 162, in which the chip windows are punched out for receiving the chips with the chip modules. After punching, the film is fed to the stapling console 156. At the same time, a carrier web is guided under the film punching station 162 to the stapling cone 156. In the stapling console 156, the film and carrier web are stitched together to a utility 150 and further conveyed to the placement console 158. In the assembly console 158, the chips punched out by the module punching station 164 with the chip modules are inserted into the chip windows. Subsequently, the wire windings in the laying console 160 are laid on the utility 152 and connected to the chips in the contacting console (not shown). Finally, a protective film is fed and stapled with the benefit 152. In the cutting station 166, the utility 152 is then cut into a multiplicity of manageable processing units and removed from the machine bed 148, for example for lamination.

In the direct contacting method described under FIG. 4, the use of the laying and contacting 4, the laying console 160 and the contacting console are combined into a single console, so that the four consoles are correspondingly reduced by a factor of 1 to three consoles. It should also be noted that then the module punching station 164 does not punch out the chips with the chip modules, but only the chips, as can be dispensed with the chip modules as described in Figure 4. Accordingly, an adaptation of the foil dancing station 162 is required in order to reduce the area of the chip windows to be punched out.

Depending on the material of the film, it may be advantageous to improve the adhesion of the wire windings on the film to provide the film with a coating prior to laying the wire. The coating makes it possible to use materials for laying wire windings, which are only of limited suitability due to their poor installation properties. An exemplary material is Teslin®, which is known for its very good weathering, temperature and moisture resistance, but only allows poor adhesion of the wire windings. When applying a corresponding coating, however, the adhesion can be improved in such a way that films made of this material also permit very good wire laying.

The application of the coating can take place over the entire surface or in certain areas, such as, for example, the wire insertion areas, of the film. An exemplary coating thickness is about 30μm. The coating material preferably cures under ultraviolet light. An exemplary coating material is polyethylene. The application of the coating takes place in a coating station 163 by means of, for example, a spray, brush, doctor blade, screen printing, pad printing or metering technique as shown in FIG. 5 according to FIG Window punching station 162 and in front of the stitching station 156. However, it is also conceivable, depending on the selected coating technique, to arrange the coating station 163 between the stitching console 156 and the mounting console 158.

To harden the coating, it is advantageous if the stapled-together benefit 150 in front of the mounting console 158 passes through a buffer zone, for example in the form of a U-shaped arc, before it is fed to the mounting console 158.

FIGS. 6 and 7 show a second embodiment of a manufacturing installation 168 according to the invention. As in the above-described manufacturing installation 148 according to FIG. 5, consoles 156, 158, 160 for receiving the machining stations according to the invention are arranged on one side of a machine bed 150. The consoles 156, 158, 160 have the same structure and the same possibilities of movement in the x, y and z directions as those of the production system 148 according to FIG. 5, so that no repeating explanations are given in this regard Reference is made to the above explanations.

An essential feature of this manufacturing facility 168 is that a plurality of transponder units 184 are fabricated from individual sheets 174 that are manually laid on carriages 172 and pass through the individual consoles 156, 158, 160, with the sheets 174 returning after processing guided to the starting position and there manually removed from the carriage 172. That is, the sheets 174 are guided in a circle, wherein the placing on the respective carriage 172 or its bearing surface 186 and the removal of the respective carriage 172 manually via an operator 176 takes place. To illustrate this circular movement of the bows 174, arrows are shown in FIG. Due to the manual handling of the sheets 174, this production plant 168 is particularly suitable for individual small series. According to the right-hand arch 172 in FIG. 6, for example, one sheet 172 can be used to produce sixteen tranpond units 184.

The carriages 172 for accommodating the sheets 174 to be loaded are movably mounted on the machine bed 150 via a feed 170. In the present embodiment, the sheets 174 are prepared in such a way that they already have windows for receiving a respective chip. The sheets 174 are manually placed on the respective carriage 172 at the starting position by the operator 176 and moved via the carriage 172 successively to the individual consoles 156, 158, 160. As shown in FIGS. 6 and 7, the carriages 172 move from left to right. For example, the chips for the supersonic units 184 can be laid in the windows on the first console 156, the wires 4 on the transponder units 184 laid on the second console 158, and the wires 4 can be connected at their ends to the respective chip on the third console 160 become. The application of a protective film can be carried out manually after the return of the sheets 174 to the starting position and after the removal of the sheets 174 by the operator 176.

For returning the assembled sheets 174 to the operator 176, ie for moving the carriages 172 according to the illustrations in FIGS. 6 and 7 from right to left, a return 178 is provided, which is preferably located in an inner space 180 of the machine bed 150 according to FIG 7 runs below the feed 170. The feedback 178 is connected to the feed 170 via a respective lifting device, not shown, end for lowering and lifting the carriage 172 in connection. When lowering a carriage 172 this, after he has passed through the brackets 156, 158, 160, passed with the assembled sheets 172 from the right end of the feed 170 according to FIG. 7 to the return 178. Upon lifting, this carriage 172 is moved from the left end portion of the return conveyor 178 shown in FIG. 7 back to its home position at the operator 176 so that the operator 176 removes the loaded sheet 174 from the lifted carriage 172 and a new one on this then free carriage 172 sheet 174 to be machined can be placed, which can then be fed via the feed 170 to the individual consoles 156, 158, 160.

In order to prevent slippage of the sheet 174 on the bearing surface of the carriage 172, according to FIG. 8 a mechanical clamping device 188 and a magnetic clamping device 190 can be provided, by means of which the sheet 174 is located at edge regions extending away from one another and extending in the feed direction 192, 194 releasably on the support surface 186 of the carriage 172 is clamped.

The mechanical clamping device 188 has a clamping claw 196 rotatably mounted on the carriage 172, which is biased against the surface 200 of the sheet 174 via a biasing spring 198 in clamping position. The prestressing spring 198 is partially accommodated in a recess 202 on a narrow side 204 of the carriage 172, wherein it acts on a rotary leg 206 connected to the clamping claw 196.

For placing a sheet 174 on or for removing a sheet from the carriage 172, an unillustrated opening mechanism, preferably a pneumatic cylinder, can be actuated by the operator 176 in such a way that that according to the view. 8, the clamping claw 196 performs a counterclockwise rotation against the biasing force of the biasing spring 198 so that the clamping claw 196 is spaced from the support surface 186 of the carriage or from the surface 200 of the arc 174. The opening mechanism can of course also be operated in other ways, such as hydraulically, electromotively or electromagnetically.

The magnetic clamping device 190 has a terminal strip 208 to be handled by the operator 186, in which a cavity 210 for receiving a magnetic strip 212 is formed. For clamping the sheet 174 at its edge region 194, a projection 214 is provided, which is spaced when placing the clamping bar 208 on the support surface of the carriage 172 thereof, so that a receiving pocket 216 is formed for receiving the edge portion 194. The clamping bar 208 is freely movable on the carriage 172, which is magnetizable accordingly, and is held only in its current position by the magnetic force of the magnet belt 212. Due to the free positioning of the clamping bar 208 on the carriage 172, sheets 174 of different dimensions can be securely clamped on the carriage 172 in a detachable manner.

Disclosed is a laying device for laying wire windings in transponder units with an axial wire feed to the laying device, a contacting device for contacting the wires with an automatic Thermodenklemmanordnung, a Zustell¬ system for feeding processing devices with a piezo-leg motor, a manufacturing plant for Her¬ position console-type transponder units, a process for the production of transponder units with horizontal ultrasound introduction and a transponder unit, in which the wire ends directly on the connection surfaces of the chip attack.
